The impacts of diagenesis on the geochemical characteristics and Color Alteration Index of conodonts Vrije Universiteit Brussel

Martyn Golding, Rhylan McMillan

The conodont Color Alteration Index (CAI) has been widely used to determine the maximum temperature in carbonate rocks, despite recognition that conodont colour can be affected by other factors, such as diagenesis. Measurements of trace element characteristics in conodonts of varying CAI (1.5–6.0) from the Canadian Cordillera show that those specimens with the most anomalous CAI with respect to independent estimates of maximum temperature ...

Temporal and palaeoclimatic context of the evolution of insular woodiness in the Canary Islands KU Leuven

Alexander Hooft van Huysduynen, Steven Janssens, Vincent Merckx, Rutger Vos, Luis Valente, Alexander Zizka, Maximilian Larter, Betul Karabayir, Daphne Maaskant, Youri Witmer, et al.
Insular woodiness (IW), referring to the evolutionary transition from herbaceousness toward woodiness on islands, has arisen more than 30 times on the Canary Islands (Atlantic Ocean). One of the IW hypotheses suggests that drought has been a major driver of wood formation, but we do not know in which palaeoclimatic conditions the insular woody lineages originated. Therefore, we provided an updated review on the presence of IW on the Canaries, ...

Habitat isolation and the cues of three remote predators differentially modulate prey colonization dynamics in pond landscapes Vrije Universiteit Brussel

Jayme M. Santangelo, Bram Vanschoenwinkel, Hendrik Trekels

Recent evidence suggests predators may change colonization rates of prey in nearby predator-free patches as an example of context-dependent habitat selection. Such remote predator effects can be positive when colonizers are redirected to nearby patches (habitat compression), or negative when nearby patches are avoided (risk contagion). However, it is unknown to what extent such responses are predator- and prey-specific and change with ...

The Pupal Parasitoid Trichopria drosophilae Is Attracted to the Same Yeast Volatiles as Its Adult Host KU Leuven

Gordana Ðurović, Francine van Neerbos, Sofie Bossaert, Beatriz Herrera, Jan Steensels, Judit Arnó, Felix Wäckers, Islam Sobhy, Kevin Verstrepen, Hans Jacquemyn, et al.
There is increasing evidence that microorganisms, particularly fungi and bacteria, emit volatile compounds that mediate the foraging behaviour of insects and therefore have the potential to affect key ecological relationships. However, to what extent microbial volatiles affect the olfactory response of insects across different trophic levels remains unclear. Adult parasitoids use a variety of chemical stimuli to locate potential hosts, including ...

Interactive spatial planning of urban green infrastructure – Retrofitting green roofs where ecosystem services are most needed in Oslo Vrije Universiteit Brussel

Zander S. Venter, David N. Barton, Laura Martinez-Izquierdo, Johannes Langemeyer, Francesc Baró, Timon McPhearson
Spatial multi-criteria decision analysis (MCDA) is increasingly being used to inform urban green infrastructure planning. We explore the use of modern cloud computing technologies (Google Earth Engine) to facilitate public access to spatial MCDA of ecosystem services from green infrastructure. Using the spatial prioritization of green roof retrofitting in Oslo, Norway, as a case study, we present a web application that is a generalizable tool ...
